KALAMAZOO TOWNSHIP, Mich. (WOOD) — Police are looking into the “suspicious” death of a man whose body was found in a house fire Saturday night.

Around 8 p.m., fire crews with the Township of Kalamazoo Fire Department were sent to the area of Shakespeare Avenue and Egleston Drive for a house fire.

Responding crews quickly extinguished the fire and found the body of a 53-year-old Kalamazoo man inside the home. His name has not been released.

The Township of Kalamazoo Police Department and the Michigan State Police were called to the scene to investigate. They said they are treating the death as suspicious. An autopsy is scheduled to determine his cause of death.

A next-door neighbor found his body after seeing smoke coming from the house and called police. The neighbor told News 8 he saw a knife, a wrench and a lot of blood around the body.

“Somebody definitely killed him,” he said.

Liz Merkle, the neighbors’ wife, said the man lived there for more than 20 years.

“He lived there for a really long time and he helped everybody and he was a nice guy,” she said. “We’ve never had to worry about anything in this neighborhood until he started letting homeless people live over there with him.”

The neighbors said they have been cooperating with police and are hopeful they’ll find those responsible.

This house fire and death remain under investigation.

Anyone with information is asked to call Kalamazoo Township Police Department’s Criminal Investigation Unit at 269.381.0391 or Silent Observer at 269.343.2100.
